A recent study published in 'Engineering' investigates the behavior of lunar regolith particles collected from China's Chang'e-5 mission when exposed to an external electric field.

To replicate the lunar environment, the experiments were conducted in high-vacuum conditions using regolith samples from the Chang'e-5 mission.

The research, conducted by scientists from Tsinghua University and other institutions, focuses on the charging properties and dynamics of these lunar samples.

Findings revealed that lunar particles, ranging from 27.7 to 139.0 micrometers in diameter, acquired a more negative charge in an electric field compared to conditions found in the atmosphere.

The study also measured critical data, including the charge acquired by lunar samples and their charge-to-mass ratio, which is essential for future lunar engineering applications.

Significant damage was observed on target surfaces impacted by charged lunar particles, highlighting the risks that lunar dust poses to aerospace materials.

These findings are crucial for designing protective measures for spacecraft and lunar structures, thereby enhancing safety in upcoming missions.

Moreover, the study aims to improve the understanding of lunar regolith resource utilization, which has important implications for space exploration.

The research provides foundational insights that could lead to the development of new techniques in in-situ resource utilization, essential for establishing sustainable lunar bases.

Overall, this study fills a significant gap in experimental data regarding lunar particle behavior and promotes strategies for sustainable lunar exploration.
